摘　　要：为了探求管-杆伸出式侵彻体的威力增益规律,在相应侵彻试验的基础上,利用LS-DYNA3D建立了管-杆伸出式侵彻体垂直侵彻和60°着角斜侵彻的数值模拟模型,并与基准杆的侵彻情况进行了对比分析。结果表明,管-杆伸出式侵彻体与基准杆相比,垂直侵彻与着角60°的斜侵彻均有9%以上侵彻的增益,着速大于1 600m/s时增益随着速的增长而增长,且斜侵彻时的增益同比大于垂直时的增益,斜侵彻最大增益达19.5%。In order to explore power-gain law of the penetrator with an extended tube-rob, the numerical simulation model of the penetrater penetrating obliquely at 60° impact angle and vertically was established by LS-DYNA3D based on corresponding penetration experiments. The penetration results of extended penetrator was compared with that of baseline rod. The results show that the extended penetrator is more efficient by above 9% both in normal penetration and oblique penetration with 60° impact angle. The gain increases with the increase of impact speed while impact speed is greater than 1.6 km/s. The gain of oblique penetration is greater than that of the normal penetration,and the maximum gain of oblique penetration can be up to 19.5%.
